IMPROVEMENT IN SUGAR COOLING AND DRAINING APPARATUS.

Specification forming part of Letters Patent No. 166,778, dated August17, 1875; application filed June 5, 1875.

To all whom it may concern: 7

Be it known that I, J osEPH H. HYNSON, of Alexandria, in the parish ofRapides and State of Louisiana, have invented a new and usefulImprovement in Sugar Cooler and Drainer, of which the following is aspecification:

In the accompanying drawing, Figure 1 represents a perspective view ofmy improved cooler and drainer, with part broken out to show interior;and Fig. 2 is a vertical transverse section of the same on the line as00, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention relates to an improved sugar cooling and drainingapparatus. by which the cooling and granulating of the sugar and thedraining otf of the molasses are accomplished in superior manner, and bysimple and inexpensive means.

The invention consists of an oblong coolingvessel, with bottom inclinedfrom both sides toward the center, where a longitudinal slot connectswith a slotted revolving drainingtube, fitting tightly to the under sideof the central bottom part of the vessel.

In the drawing, A represents an oblong vessel for cooling sugar, whichcorresponds in size with the kettles from which it is charged. Thevessel is preferably made of wood, and filled gradually by the strikesfrom the kettles, a certain time being allowed to elapse between eachstrike for the granulating and cooling of the sugar before anotherstrike is emptied on the same, and so on until the cooler is full. Thebottom of the cooler is inclined from the sides toward the longitudinalcenter, for the purposes of allowing the molasses to drain to the lowestpart of the center. A longitudinal slot, a, runs through the center ofthe vessel, and connects with a draining-tube, B, closed at both endsand slotted at diametrically opposite points throughout its full length.The draining-tube B turns by a crank, B, at one or both ends in asleeveshaped attachment, D, which isalso slotted at the lowest point inlongitudinal direction, or in other suitable bearings, but so that aperfectly tight contact of the slotted bottom partof the cooler andrevolving tube is formed. When, after the striking is finished, thesugar in the cooler has sufficiently granulated, the process of drainageis commenced by turning the crank until the slotted part of the tubeopens gradually toward the bottom slot of the cooler. If the sugar isstill warm the molasses drains rapidly through the narrow crevicewithout allowing any of the grains of sugar to pass; but if the sugarhas cooled and become firmer the opening between tube and bottom slotmay be opened wider for the readier draining of the molasses which hascollected by granulation at the central bottom part of the cooler. Themolasses may in this manner be drained olf more or less rapidly,according to the degree of heat in the sugar. The most advantageousmoment for draining may thus be readily determined, so that a betterquality of sugar than with the common modes of draining may be obtained.

Having thus described my invention, I claim and desire to secure byLetters Patent A sugar cooler and drainer composed of a coolingvesselhaving bottom inclined. from the sides to the central longitudinal slot,in connection with a tight-fitting revolving draining-tube, providedwith corresponding slots at diametrically-opposite points, substantiallyas and for the purpose set forth.
